20100104030 | COMMUNICATIONS DEVICE AND COMMUNICATIONS METHOD - A communications device | 04-29-2010 |
20110090067 | COMMUNICATION APPARATUS ENABLING COEXISTENCE OF SYSTEMS - A frequency band is divided into N subchannels. Sub-channels are first allocated for a power line communication system having a higher priority, such as public communication or the like. Sub-channels for a power line communication system having a relatively low priority, such as in-home communication or the like, are allocated from free subchannels. In this case, the subchannels used by the power line communication system having the high priority are limited to a plurality of consecutive subchannels from an upper side or a lower side of the frequency band. | 04-21-2011 |
20110222554 | COMMUNICATION APPARATUS ENABLING TEMPORAL COEXISTENCE OF SYSTEMS - A coexistence controller which performs management and control of time division for coexistence, is provided in a power line communication modem which has a function as a QoS controller for a QoS type communication system and a power line communication modem for a best-effort type communication system. In the QoS type communication system, by controlling allocation of a communication band in accordance with priorities given to the communication systems by cooperation of the coexistence controller and the QoS controller, the power line communication systems having different schemes can coexist. | 09-15-2011 |
